word中的图片如何保存为jpg格式_把word导出成图片的流程

word中的图片如何保存为jpg格式_把word导出成图片的流程 由于工作中需要从大量docx文档中提出图片，于是到网上搜索，找了一大堆都是分析xml文件并提取的，太过于复杂，实际上有更简单的方法，我们需要用到python-docx这个第三方库，但该库并未开发提取图片功能，不过可以通过其他方法出得到图片数据并保存为图片。

软件界面下面这段代码是核心： for file in os.listdir(filePath): try: #跳过非docx文件 if ".docx" not in file: continue # 创建imgPath subImgPath = imgPath + re.sub(".docx","",file) if not os.path.exists(subImgPath): os.makedirs(subImgPath) doc = docx.Document(filePath + file) #打开文件 for rel in doc.part._rels: rel = doc.part._rels[rel] #获得资源 if "image" not in rel.target_ref: continue imgName = re.findall("/(.*)",rel.target_ref)[0] with open(subImgPath + "/" + imgName,"wb") as f: f.write(rel.target_part.blob) UI.currentFile.setText("当前文件：" + imgName) except: continue

后来经过改进，使用PyQt5制作了界面，下面为源代码：import docx,re,os,sys,ui_imgExtractfrom PyQt5.QtWidgets import QApplication,QMainWindow,QWidget,QMessageBoxfrom PyQt5.Qt import QFileDialogdef run(): filePath = UI.filePath.text() imgPath = UI.imgPath.text() if not os.path.exists(filePath): QMessageBox.about(main, "错误", "请选择docx文件目录！") return if not os.path.exists(imgPath): os.makedirs(imgPath) for file in os.listdir(filePath): try: #跳过非docx文件 if ".docx" not in file: continue # 创建imgPath subImgPath = imgPath + re.sub(".docx","",file) if not os.path.exists(subImgPath): os.makedirs(subImgPath) doc = docx.Document(filePath + file) #打开文件 for rel in doc.part._rels: rel = doc.part._rels[rel] #获得资源 if "image" not in rel.target_ref: continue imgName = re.findall("/(.*)",rel.target_ref)[0] with open(subImgPath + "/" + imgName,"wb") as f: f.write(rel.target_part.blob) UI.currentFile.setText("当前文件：" + imgName) except: continue QMessageBox.about(main, "完成", "图片提取已完成！")def init(): UI.btnRun.clicked.connect(run) #绑定开始提取按钮 UI.btnFilePath.clicked.connect(choiceFileDir) # 绑定选择docx文件目录 UI.btnImgPath.clicked.connect(choiceImgOutPutDir) #绑定选择图片保存目录 # docx文件默认目录 UI.filePath.setText(os.getcwd()) #默认输出目录 if not os.path.exists(os.getcwd() + "img\"): os.makedirs(os.getcwd() + "img\") UI.imgPath.setText(os.getcwd() + "img\")#选择docx文件目录def choiceFileDir(): dir = QFileDialog.getExistingDirectory(main, "选择docx文件目录", os.getcwd()) UI.filePath.setText(dir + "/")#选择图片保存目录def choiceImgOutPutDir(): dir = QFileDialog.getExistingDirectory(main, "选择输出目录", os.getcwd()) UI.imgPath.setText(dir + "/")if __name__ == "__main__": app = QApplication(sys.argv) main = QWidget() UI = ui_imgExtract.Ui_Form() UI.setupUi(main) main.show() init() sys.exit(app.exec_())下面是界面文件ui_imgExtract.py：# -*- coding: utf-8 -*-# Form implementation generated from reading ui file 'ui_iask.ui'## Created by: PyQt5 UI code generator 5.11.3## WARNING!
